Large-cupped daffodil (Division II). Large-cupped daffodils are perhaps the most popular of the twelve daffodil divisions. By definition, a large-cup daffodil features a cup (corona) that is more than 1/3 but less than the length of the petals (perianth segments). ëSlim Whitman rises 14-16î tall in spring. Each flower features creamy white petals and a slightly ruffled, orange to yellow-orange cup. One flower per stem. Blooms early-midseason (March-April in St. Louis). Narrow, linear to strap-shaped, green leaves in erect to sprawling clumps. Excellent fresh cut flower. Cultivar honors country singer of the same name.
- Full sun to part shade
Easily grown in average, medium, well-drained soil in full sun to part shade. Best in organically rich, sandy to loams that drain well. Plant bulbs 4-6\ deep and 3-6î apart in fall. After the flowers have bloomed, the top portion of each flower stem may be removed, as practicable, to prevent seed formation, but foliage should not be cut back until it begins to yellow. Flowers usually face the sun, so bulbs should be grown with any shade areas at the rear of the planting. Bulbs can be left undisturbed for a number of years."
